Metronome EXP takes the concept of a metronome and expands it with a host of features aimed at the practicing musician. Its accurate timing engine can play anything from a simple beat to complex drum patterns via the built in step sequencer. Virtually all time signatures are supported. Other features include a versatile speed trainer, presets, 12 instrument voices that use either midi or user supplied 44.1kHz 16-bit audio files, and much more.
